The contact elements 71 are carried-by afbar72 provided with a rearwardly extending arm 7 3, pivoted at 7 4 to the frame and rigidly connected with a l link 75, in turn connected with a vertical con-' 7 necting rod 76, securediat its lower endto a V otally connected at 80-witha frame :part 80', said lever having av pedal 79 atits forward enda'nd being normally held in raised-pos1- rearward extension 77 of a foot lever 78, pivti'on'by means of a spring 81, connectings'aid lever to the frame. Thus when it 'is desired to jopierate the; machine,the operator places his foot upon the pedal 79, thereby establishing contact between the-r011 4.5, and contact;

wires or brushes'71, as shown in Fig. 4,which results in playingythe instrument when: the music roll is 'fed between saidiconta ctielements, it being understood thatjthe paper serves'to insulate the contacts, exceptatthe pointswhere the perforations permit the contact elements 71to engagethe roll 452 i. It willb'enoted, from Figs. land 6. of the drawings, that I employ a scale '82,'bearing indicia of the notes ofthefi'nstrument, or. instruments, for which themusic roll is intended, these being so spaced and numbered as to facilitate identification of the perfora tionsin the sheet with the notes played theretitled with perforations for p by. The scale shown is prepared for a roll perforated for bothpiano and violinand contains,,in'addition tofthe notesplayed on the various keys and strings, certain spacesldeng roducmgxvarrous tone effects and controls;

The contact brushes 71iare connected by a series of wires 89 and 91, respectively, with magnets 87 and 88ofan electric piano and an electric violin (either or both may be used) and saidinagnets are in turn connected'with the negative side of the line through a three way switch 92; Thus when the foot peda17 9 y to the down position,.the player mechanism f r isready to operate whenthe music roll isfed over the' roll 45.

The motor 67.;isconnected'by a i wire 7 0 with a contact element 10carried by fand' 'insulated from the brush carrier bar 72.: Said" cont-act element 104is adapted to- .engage a contact element'103on the frame whenthebar 7 2 is in the down position. The

contact element 103 is connected by 'a wire with a switch 85, connecting with the pos-.

itiveside of the line. Thus when the switch Referring now "to Fig. 5 of-the drawingd.

When a falsenote is detected, the. forward feed may be stopped by releasing the foot lever 79, thus breaking the contact 104;, 103.

This makes contact between two contact elements 107 and'108 carried'respectively upon the frame, and thebar 72 and properly in sulated. The contact 108 is connected by a" wire 84: with the negative side of the lineand the eontact107 by a wire 102 withthe motor.
